Specification of LettersPatent.

Patented Mar. 17,1914.

Application led April 2l; 1910. Serial No. 556,780.

of lVorcester, county of Worcester, and State of Massachusetts, have invented a new and useful improvement in Clotl1-Pressing Machines, of which the following is a specification. A

The primary object of this invention is the simpliiication and lightening of the machine shown in my Patent No. 565,072 dated August 4, 1896.

Figure 1 is an elevation of the gear or` right hand end of the machine with the bed in pressing position. Fig. 2 is an elevation of the steam or left hand end of the machine with the bed in pressing position; the lowered position of the bed plate being shown in dotted lines. Fig. 3 is an eleva tion of the front of the machine with the Fig. 4 is an elevation of folder omitted. the rear of the machine with the folder in position. Fig. 5 is a plan view. Figs. 6, 7 and 8 are details.

The shaft 23 from which the bed pla-te pressure is produced, is operated from the hand wheel 23e, through the pinion 23b and gear 2. C, pinion 23d and segmental gear 23e. The shaft 58 from which the cylinder is driven is driven by power applied through the fast and loose pulleys' 58ZL and 58h. In

lieu of any base plate, 1 use the girds 1a, 1b, l 1C, 1d. There are two members of the frame each of which consists of two boxed uprights 2 and 3 and a connecting member 4 at the top. At the gear end of the machine,

a web 5 connects the uprights 2 and 3 butI at the steam end the uprights 2 and 3 are unconnected so as to leave a clear open space;

A between them for the removal of the bed plate and its truss. The cylinder 7 is mount ed in stationary bearings upon the mem-v bers 4. The bed-plate 8 is located immediately below the cylinder and is provided with end projections 9 and 10 which project into the members 2 and 3 and slide vertically in guideways on the members 4, whereby said bed plate is movable radially of the cylinder 7. Each of the bed plate projections 9 and 10 rests upon the crown of a stud 11 screwthreaded to the worm gear 12, which rests upon the top of a hollow column 13, which is pivoted to a lever 14 having its fulcrum on the frame at 15 and opera-V i tively connected by a link 16`with an arm 17 fixed to the shaft- 23.

The bed plate is so arranged that the central line of its pressing surface is in substantially the same vertical plane with the cylinder axis.

The movement for producing and releasing the bed plate pressure is produced through the connections last referred to by the oscillation of the shaft 23. As the shaft 23 is moved from the nonpressing position shown in Fig. S, to t-he pressing position shown in Fig. 6, the arm 17 and link 16 perform the power-multiplying and locking function of a toggle and the power is further multiplied by the lever 14.

In releasing the pressure, the first movement of the arms 17 serves to move the toggie 16, 17 out of its locked position of Fig. 6. Thereupon, it is necessary to apply a brake to stop the release at the desired point and prevent it going too fast. This brake is shown at 40 and is held normally set by a spring 41. It is unset by a foot lever 42. The operator by the use of this brake can regulate the speed of release and stop it at any point desired.

I understand this to be the iirst machine in which retraction of the bed plate, after being unlocked, from pressing into nonpressing posit-ion is actuated automatically by the weight of the bed plate so that after the operator performs the unlocking, the weight of the bed plate does the vrest until the retractive movement is stopped by the operator. 1n the machine shown the operator unlocks the toggle by a slight movement of the hand-wheel 23, Thereupon, the bed plate descends under its own weight and it remains only for the operator to control the speed and extent of its descent by the footlever 42 through the brake 40.

Fixed so as to move with the pinion 23" is a project-ion or nose 43 with which a dog 44 is adapted to engage when in the position shown in Fig. 6, so as to stop the movement of the hand wheel 23a. This dog 44 is held normally out of engagement with the projection 43 by a spring 45 but is thrust into engaging position by a projection 46 cast on the segment gear 23e contacting with an adjusting screw 47 on the arm 48 fixed to the dog. By the adjustment of the screw 47, this mechanism may be set so as to stop itself as soon as the operator has moved the toggle 1G, 17, into the position shown in Fig. G where it is in the pressing position desired.

The movement for adjusting the bed plate pressure is produced by turning the hand wheel 18 and thereby, through the 'worm gears 19 and 12 controlling the adjustment of the stud 11. The movement forlowering the bed plate to the positio-n for its removal from the machine is produced by continuing the movement of the hand wheel y18. lVhen this movement has continued until the bed plate slides 30, 31, rest on the ledges 22, 24, the studs 11 will be relieved of the weight of the bed plate and the bed plate may be slid endwise out through the opening A and supported during such slid ing by the ledges 22 and 24. lVhile so supported and being slid, the truss of the bed plate will extend down into the space between the ledges 22 and 24. These ledges are carried by brackets Xed to the frame members 2, 3, on opposite sides of the opening A and extending, as shown in F ig. 3, part way toward the opposite end of the frame.

As the bed plate descends, the downward projections 2O and 21 from the bedplate descend bet-ween the ledges 22 and 24 so as to guide the bedplate in its downward movement. Then the downward projections 32 and 33 from the bedplate descend outside the ledges 22 and 24 so that as the bedplate is slid out endwise on the ledges 22 and 24 they are held between the downward projections 30, 31, and 32, 33, respectively, and the bedplate is thereby held to a straight path.

60 is an endless apron extending between the cloth being pressed and the bed-plate and thence over the driven draft roll 61, the regulator roll 62, the tension or take-up roll 63, the idler rolls 64 and 65 and the roll G6. The tension or tale-up roll 63 is mounted on a slide G7 adjustable by the screw 68 at each end. The regulator roll 62 is mounted upon a swiveling support G9 enabling the axis of the roll to be swung in a plane substantially at right angles with the apron so as to cause it to bear more heavily against one side or the other of the apron as may be desired.

The fact that the bracket ledges 22 and 24 extend on opposite sides of the bed plate truss only part way from one end frame to the other, provides a rest for the bed plate while change of aprons is being made, which neither interferes with the transfer of the apron nor with the bed plate truss.
